Dab tsi yuav tsum tau raug sau tseg thaum txhim kho thermocouples?

Thermocoples tau siv dav hauv lub neej txhua hnub, tab sis tsis paub meej txog qee yam kom xyuam xim thaum txhim kho cov twj paj nruag no. Thaum lub sij hawm cov txheej txheem kev teeb tsa, thermocouples yuav tsum tau them sai sai rau qee yam. Nws tsis yog qhov tsis yooj yim dua kom tsis txhob xyuam xim rau lawv, tab sis tseem ceeb dua kom them sai sai rau cov ntsiab lus thaum txhim kho lawv. Cia peb tham me ntsis txog qee yam kom them sai sai thaum txhim kho thermocouples hauv kev siv.

1. Kev teeb tsa qhov chaw. Lub installation ntawm thermocouples yuav tsum kaw kom ze li sai tau rau qhov ntsuas kub thiab txias yog nyob rau hauv nruab nrab ntsuas thiab deb ntawm muaj zog sib nqus thiab hluav taws xob. Kev xaiv qhov ntsuas kub ntsuas rau cov ntsiab lus thermoco yuav tsum yog tus sawv cev thiab yuav tsum tsis txhob muab tso rau hauv cov cheeb tsam uas ntsuas nruab nrab tsis tshua pom. Thaum ntsuas qhov ntsuas kub ntawm cov roj hauv lub raj dej, cov thermocouple yuav tsum tau muab tso tawm tsam cov kev taw qhia ntws; Thaum ntsuas qhov ntsuas kub ntawm cov dej hauv lub raj dej, ntsuas qhov kawg ntawm lub rooj zaum siab, thiab qhov kawg ntawm nws txoj kev tiv thaiv lub tes tsho yuav tsum hla ntawm nruab nrab ntawm cov nrawm; Thaum ntsuas qhov ntsuas kub ntawm cov khoom, ntsuas qhov kawg ntawm lub thermocouple yuav tsum raug ntsuas, thiab qhov ntsuas kub nyob ze rau qhov ntsuas cua sov ua kom tsawg zog.

2. Qhov tob ntawm cov ntxig. Thaum txhim kho ib qho thermocouple, nws yuav tsum tau raus hauv qhov nruab nrab ntsuas rau ib qho tob. Feem ntau, thaum siv cov hlau tiv thaiv hlau, lub ntxig ntxig yuav tsum yog 15-20}} sij hawm nws txoj kab hla; Thaum siv cov quav uas tsis yog xim hlau tiv thaiv, lub ntxig ntxig yuav tsum 10-15 lub nroog.

3. Thermal hluav taws xob hluav taws xob. Thaum muaj ib qho khoom loj nrog qhov sib txawv kub sib txawv nyob ze ntawm thermocouple, qhov thermocouple yuav tau txais hluav taws xob hluav taws xob. Qhov ntsuas kub ntawm qhov ntsuas kub ntawm cov kev ntsuas ntsuas ntsuas ntsuas, thiab cov ntaub thaiv hluav taws xob kom tau siv los ua kom muaj cua sov rau cov pa hluav taws xob, uas yog thaiv thermocouple yuav siv tau.

4. Txoj haujlwm ntawm cov xov hlau them. Them cov xaim xaim xaim txog cov xov tooj ntawm cov xov hlau insulated uas txuas rau lub thawv thermocouple sib txuas nrog cov ntsuas kub. Kev siv cov xov hlau tsis tuaj yeem tsuas yog siv cov ntsuas cua sov, txhim kho cov ntsuas cua sov thiab cov ntsuas kub uas muaj qhov kub thiab txias, txhim kho cov ntsuas cua sov tas li, thiab ua lub luag haujlwm ntawm kev them nyiaj rau qhov kub thiab txias. Kev siv cov xov tooj hluav taws xob yuav tsum tau sau tseg tias qhov ntsuas kub ntawm ob cov ntsiab lus sib txuas yuav tsum yog tib yam thiab tsis ntau tshaj 200 degree c rau cov hom cua sov-resistant). Nyob rau tib lub sijhawm, nws yuav tsum tau kom meej meej tias cov polarity tsis tau thim rov qab thaum txuas rau cov hluav taws xob ntev hauv hluav taws xob lub zog ntawm cov hluav taws xob thiab nce qhov ntsuas kub ua yuam kev.
